Objective To understand the occupational health status and the impact on the health of workers in machine spinning asbestos,and to provide scientific basis for prevention and control of relative occupational diseases.
Methods A total of 8 enterprises were investigated.The occupational health survey included detection and evaluation of asbestos dust concentrations,as well as occupational health inspection of 183 workers exposed to asbestos.
Results The asbestos dust concentrations were higher than the national standard except 2 points qualified in 25 monitoring points.3 workers were diagnosed as suspected asbestosis,9 were observed objects and 37 were abnormal lung markings among the 183 workers.Each selected enterprise installed a mechanical ventilation/dust removal system and 2 to 4 spray devices.Each worker received two sets of working clothes and a dust mask per month.
Conclusion Occupational hazards and severe health effects are found in machine spinning asbestos industry.Current personal protective equipment and protection facilities are imperfect.Health supervision of asbestos spinning enterprises should be strengthened,in order to improve the working environment and protect workers' occupational health in future.
